I have a cheap laptop from the bay, an HP Elitebook 8540p. Im trying to upgrade the memory. it has 2 slots (i5 only has 2 slots i7 has 4) it shipped with 2gb, i have tried 2x4gb, 1x 2gb and 1x 4gb, and 1x 8gb.
It works fine with 2gb, but any other combination and it will rarely post boot. if it does it will blue screen and wont come back on until i remove the module and return to 2gb. The only error on the blue screen that i have caught is internal power failure. Is it possible that the 90w HP PSU i had (the laptop didnt ship with one) isnt enough and the extra RAM is pushing it over that? and i need the 120w PSU. I find it hard to believe that all the other memory modules i have tried are faulty.
